Arundhati Roy is a novelist, activist and a world citizen. She won the Booker Prize in 1997 for her first novel The God of Small Things. Since then, she has concentrated her writing on political issues. In response to India's testing of nuclear weapons in Pokhran, Rajasthan, Roy wrote The End of Imagination, a critique of the Indian government's nuclear policies. It was published in her collection The Cost of Living, in which she also crusaded against India's massive hydroelectric dam projects in the central and western states of Maharashtra, Madhya Pradesh and Gujarat. She has since devoted herself solely to nonfiction and politics. Roy was awarded the Sydney Peace Prize in May 2004 for her work in social campaigns and advocacy of non-violence. In June 2005 she took part in the World Tribunal on Iraq. In January 2006 she was awarded the Sahitya Akademi award for her collection of essays, 'The Algebra of Infinite Justice', but declined to accept it.
